Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] 1. Screening of TWC2

[0022] The TWC2 strain was isolated from the leaves of Taiwan grass plants in Danzhou City, Hainan Province, my country. The specific method: cut leaf tissues with a diameter of about 5mm×5mm on a sterile ultra-clean workbench, Disinfect the surface with 75% alcohol and 0.1% mercuric chloride for 30 seconds, wash it with sterile water for 3 times, transplant it onto the potato dextrose agar plate medium, and cultivate it in a 28°C incub...

Abstract

The invention relates to the technical field of microorganisms and fermentation, in particular to bacillus amyloliquefaciens and application thereof to prevention and treatment of sugarcane red rot. The bacillus amyloliquefaciens TWC2 is preserved in China General Microbiological Culture Collection Center on 19th October, 2015, and the preservation number is CGMCC No.11515. The bacillus amyloliquefaciens TWC2 is separated out of tropical grass Taiwan grass leaves, and an environment-friendly, simple and effective way is provided for prevention and treatment of the sugarcane red rot. The bacillus amyloliquefaciens TWC2 is a strain with good biocontrol application prospects, and due to the fact that the strain is separated out of the surfaces of plants, the strain has natural harmonious compatibility with natural ecology. Compared with chemical pesticide, no toxic or side effect is caused to soil ecology, no residue exists, and therefore potential business development and application value is achieved in disease biological control practice.

Description

technical field [0001] The invention relates to the technical field of microorganisms and fermentation, in particular to a bacillus amyloliquefaciens and its application in preventing and treating sugarcane red rot. Background technique [0002] Sugar cane is the most important sugar crop, and sucrose accounts for more than 70% of the world's total sugar production and more than 90% of my country's total sugar production. Sugarcane is also one of the most important renewable energy crops due to its high biomass and fiber. Sugarcane disease is one of the important factors affecting sugarcane yield and sugar content. Sugarcane red rot caused by Fusarium anthracnose bacterium Colletotrichum falcatum Went is one of the most important diseases in sugarcane production in the world. The disease not only affects the yield, but its pathogenic bacteria can also promote the conversion of sucrose, thereby reducing the purity of cane juice and reducing the sugar content of sucrose. ...
